I'm trying to run Ceph on (micro)K8s which running on my Ubuntu WSL distory.

OSD pods are not being created because there is no supported device is available (see logs below).

Ceph is configured to UseAllDevices which you can see it searching for one in the log above.

Ceph ideally wants an unformatted partition which I created on my windows host but I'm unsure how I mount that to /dev/sd{c} or do try to create a new partition within WSL itself?

I don't know how to do either or if that is even the right approach.

Thanks in advance.
